– Rare / Uncommon / Scarce
– easy to identify, generally distinctive and unlikely to be confused with other species.ID pointers: One of a few “Thorns” that are very similar. The August Thorn can be distinguished by the shape of the cross-lines on the forewing. The inner line is noticeably curved, and the outer-line has a “kink” in it where it meets the leading edge. Also note the white “Knee Socks” on the legs – September Thorn has yellow “Knee Socks”.
Distribution: (Last record: 1 July 2025 at Chaddesden ) – A resident that is locally distributed and very scarce in Derbyshire. Easily confused with September Thorn. Very few records each year. There are currently 9 reported records between 2018 and the end of July 2024. Historical records show a similar trend, so this species has never been common in the county.

This chart summarises all available historical occurrence records collated by ISO week of the year. It reflects recorder effort and sampling distribution as well as true biological activity, and should be interpreted as an indicative pattern of seasonal occurrence rather than a statistically controlled abundance or phenology model.

Bedrock Geology ** indirectly affects moth distribution by influencing the type of habitat and food plants available in an area. In turn, this may affect the types of moths that can thrive, or where they can most likely be found.
